Darkworld.

Fallon is a gorgeous twenty-something with just a couple of flaws. For starters, she's dead. A close second, she has found herself in a new job serving as a soul huntress for an evil overlord. Fallon accepts her new role and quickly turns loose on humanity. Her sinister supervisor, Mr. Sixx, is greatly impressed. Over confident in his new student, he assigns Fallon to a forbidden case -- one that ignites terrible memories and turns her against him. Can faith and family survive an onslaught of soul-searing demons? What happens when Fallon discovers that her next target is someone that she greatly cares for?
